Why site restoration doesn’t quite mean the end

Rendering of future Wallingford site once restoration is complete.

Rendering of future Wallingford site once restoration is complete.

Check it out! We’re starting the process of site restoration in 2024. Once construction is complete, impacted areas will be restored to previous conditions across East Ballard, Fremont, Queen Anne, and Wallingford. This will include landscape restoration and repaving streets and sidewalks. But wait, what about the Ballard site? If you’ve been following along our project, you may have seen us bring up the work yet to come in Ballard.

Like in Wallingford, Ballard will need conveyance pipes. Later this year crews plan to begin construction on the conveyance pipes that will bring flows to the tunnel, and a pump station that will move flows from the tunnel to the West Point Treatment Station. Without this, the sewage in the tunnel will have no where to go. We need to complete the conveyance pipes and the pump station before we can get the tunnel up and running. This work will take some time to complete. That’s why you’ll see site restorations in 2024, but the tunnel won’t be operational until 2027.

Please visit our project website to get the most up to date information about the Ship Canal Water Quality Project in your neighborhood. Check out our Flickr albums for recent construction photos as well.

The pedestrian crossing on the south side of the intersection of Stone Way N and N 35th St is closed. Pedestrians need to follow the approved detour route and cross Stone Way N at N 34th St. A temporary pedestrian walkway is put in place after construction work hours and on weekends to allow pedestrians to cross N 35th St at Stone Way N.
